I am looking for a relay that was/is very common on Edwards control panels that were made in the 1950’s and 1960’s (PLEASE SEE ATTACHED PICTURE).
The coil on the relay has the number PP-7856 stamped on it and reads 110 ohms on my volt/ohm meter. If anyone knows where I can find these types of relays it will be most appreciated. I have also attached a picture of the Edwards control panel that the relay is on.
I have a feeling they might be Struthers-Dunn units, but I’m not sure. some companies made their own relays. May I ask where this panel came from?
Be careful with that black board in that panel. They were commonly made of asbestos.
Is the relay not working? The ohm reading seems reasonable. The contacts may need to be cleaned. If you can’t find an exact replacement, any relay with the same coil voltage and contact rating should work. Two newer style relays were added at the bottom right of the panel already.
I have an entire edwards panel like that you can have if you still need a relay. its located in St. Louis, MO.
Thank you for responding to my post. If you could please send me a picture of the control panel that shows all the components that are on the panel that would be most appreciated. You can send any pictures to: [email protected] I will continue corresponding with you that way.
Sounds good. I will get those tomorrow.
